Six U.S. tech giants saw their combined market cap shift by $2 trillion this week, driven by diverging returns from AI investments.

Huo Xing Finance reports that on August 2, the combined market value changes of six U.S. tech giants that have released earnings this week approached $2 trillion, as investors are selecting winners based on cloud business growth and returns on AI capital expenditures. The combined market value of Alphabet, Amazon, and Microsoft increased by nearly $1.5 trillion, with Microsoft adding over $600 billion, and Amazon and Alphabet each adding over $400 billion. Meanwhile, Apple’s market value declined by over $350 billion, Meta fell by approximately $85 billion, and Tesla dropped by about $7 billion. Although Apple exceeded expectations in revenue, profitability, and iPhone sales, it forecasted quarterly revenue growth of 9% to 11%, below the analyst consensus of 12%, and stated that shortages of memory chips and competition for wafer capacity will continue to constrain supply; its stock closed down over 7% on Friday. Amazon’s Q2 AWS revenue grew 37% year-over-year, the fastest pace since 2021, driving its stock up over 15% on Friday. The company also raised its 2026 capital expenditure forecast from $200 billion to $220 billion. Microsoft rose 15% on Thursday, while Meta fell 8%, reflecting a clear market divergence in assessments of their AI investment returns. Jefferies noted that the tech giants’ AI spending over the next 12 months is approaching $800 billion. The current market debate is no longer whether AI has real demand, but whether long-term profits can justify such massive investments.
